Cloud computing models
Once an organization understands its responsibilities and how they apply to operating in the cloud, it must determine how they apply to its unique scenario. Responsibilities vary and are based on numerous factors such as regional laws and the cloud computing models or services they elect to meet their business requirements. For example, infrastructure maintenance tasks are the cloud providers’ responsibility. This is similar across the cloud computing leaders – Amazon, Microsoft, and Google.
Infrastructure as a service
Organizations that elect to use IaaS decrease the complexity of procuring and managing the physical infrastructure on-premises. Each service is separate and scalable, and you only pay for what you use. Cloud computing providers such as Amazon, Microsoft, and Google manage the physical infrastructure.
